GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(709, 956) = 677804
GCD(709, 956) = ( 709 x 956 ) / 677804
= 709 / 956
= 709
Step2:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 709, 956, 651, 647 is 1
